数据中心空气冷却器性能改进的数值计算

Hear Transfer Performance Improvement of Air-Cooling Unit in Data Center by Numerical Simulation

本文通过对一数据中心空气冷却器的结构及性能参数的分析,在保持冷热流体进口条件不变的前提下,从增大换热面积,提升换热系数两个方面提出了针对该换热器的两种基本改进方案。其中方案二通道高度为6mm的情形可在相同泵功的条件下,提升换热量9%,且仅要求对原换热器芯片间的距离进行调整,对原冷却系统的整体结构并无影响。

In this paper,the heat transfer performance of an air-cooling unit used for data center cooling is analyzed.Under the condition of remaining the same inlet conditions as the original one,this paper proposes two basic improvement schemes.Scheme 2 can increase the heat transfer rate by 9%with the same pump power.This scheme only demands the adjustment of the distance between the heat exchange plates without any effect on the overall structure of the original cooling system.
